Arizona P Bergesen reports

The Arizona Diamondbacks optioned pitcher Bryan Shaw to Triple-A Reno on Sunday to make room for pitcher Brad Bergesen, who reported to the club.

Bergesen was claimed by Arizona on July 20 from the Baltimore Orioles, where he spent parts of three seasons from 2009-11.

The 26-year-old right-hander had spent all of this season with Baltimore's Triple-A affiliate in Norfolk, accruing a 4-3 record and a 4.03 earned run average over 22 games, including 10 starts.

Shaw, 24, appeared in 43 games for the D-backs this season and pitched to a 1-4 record with a 4.26 ERA and two saves.
